#Music.Sound

##Syntax Music.Sound ( frequency, duration : int )

##Description The Music.Sound statement is used to cause the computer to sound a note of a given frequency for a given time. The frequency is in cycles per second (Hertz). The time duration is in milliseconds. For example, middle A on a piano is 440 Hertz, so Music.Sound(440, 1000) plays middle A for one second.

Sounds are produced synchronously on a per process basis. This means that when a process executes a Music.Sound or Music.Play command, it stops until the command is finished. However, other processes will continue executing.

##Example This program plays a siren sound in the background.

    process siren
        loop
            for i : 100 .. 3000 by 100
                Music.Sound ( i, 50 )   % Sound note
            end for
            for decreasing i : 2900 .. 200 by 100
                Music.Sound ( i, 50 )   % Sound note
            end for
        end loop
    end siren
    
    fork siren
    � the rest of the program goes here while the siren continues �
